DOUBLE HUNG CASEMEN'I WINDOW Filed Oct. 17, 1952 34 3/ INVENTOR Ferre/Armenia /W/ @m ATTORNEY CII Patented Nov. 12, 1935 UNETED STATES PATENT orifice 1 Claim.

The invention is a window which is a combination of a double hung window in which the sash are counterweighted, and a casement window in which the sash are hinged so that they may be opened with the glass of the upper sash swinging outward and the glass of the lower sash swinging inward.

The object of the invention is to provide a window with a percent window opening.

Another object of the invention is to provide means for mounting easement windows in double hung window sash.

Another object of the invention is to provide independent hinged sections in sash of double hung windows in which the sections may readily be swung inward and outward.

Another object of the invention is to provide double hung window sash with swinging glass frames in which the frames are dovetailed to form a practically vperfect lock between the frames and lock.

A further object of the invention is to provide means for locking double hung windows with swinging sash so that the sash may be locked in the closed position.

A still vfurther object of the invention is to provide a window in which the glass may readily will appear from the following description taken in connection with the drawing, wherein:-

Figure 1 is a view looking toward the outside of the window.

Figure 2 is a Vertical section thru the frames and sash with the joints on an enlarged scale.

Figure 3 is a sectional plan thru the window showing the relative positions of the sash and window weights.

Figure 4 is a sectional plan showing one side and the center of the window on an enlarged scale.

In the drawing the window is shown as it would be made wherein numeral I indicates the window frame, numeral 2 the lower rail of the frame forming the upper sash, and numeral 3 the lower rail of the frame forming the lower sash.

The window frame may be of any type or design and may be arranged in any manner. It may be of any shape and the proportions of the height. and width may be varied to provide a window for any opening desired. In the design u shown openings and 5 are provided in the sides 'il of the frame in which counterweights E and 1 may be located, as shown. It will be understood that the counterweights may be of any shape or design and may be arranged in any manner. In

he design shown the counterweights may be l0 supported by cables 8 which pass over pulleys 9 at the upper end of the windowframe, as shown in Figure l.

The cables 8 are attached to side members III and I of the frames in which the members 2 and I5 3 form the lower or cross rails thereof. The members I and are slidably mounted in rails I2 and I3 and it will be noted that the rails have inwardly extending anges |11 and I5 which eX- tend into grooves l5 and il in the sides of the 2) members I!) and The members I and II are therefore free to move upward and downward and are connected at their lower ends by the cross rails 2 and 3 which are made integral therewith. These frames are therefore U-shaped with their 25 upper ends open and the sash are hinged to the vertical members thereof.

'Ihe upper frame with the cross rail 2 is provided with sash I8 and i9 which are hinged to the members l0 by hinges 20, and the lower 30 frame, with the cross rail 3, is provided with sash 2| and 22 which are hinged to the members by hinges 23. It will be noted that the upper sash I8 and I9 are hinged to the outside of the vertical members I@ and the lower sash are hinged 35 to the inside of the vertical members so that the sash of the upper frame will swing outward and the sash of the lower frame inward. The horizontal members of the sash may be made as shown in Figure 2 with a channel shaped section 40 24 at the top and a grooved section 25 at the bottom. It will be noted that the section 25 dovetails over the member 2 of the upper frame with the member 2 forming a tongue extending into the groove which is indicated by the numeral 2B. 45 The sections 24 and 25 are provided with beads 21 against which a glass 28 may be held by putty,

as indicated by the numeral 29, or by any other means.

The lower frame with the cross rail 3 is provided 50 with sash 2| and 22 which swing inward and it will be noted that the lower edges of these sash are dovetaled into the member 3, as shown in Figure 2. The member 3 is provided with a groove 30 in which a tongue 3| on the lower edge of the 55 sash passes and the lower edge of the sash are providedl with a groove 32 into which a tongue 33 on the member 3 passes as shown in Figure 2. It will be noted that this will form a perfect seal and at the same time rigidly lock the sash in the frame to form a rigid construction which will hold the frame and prevent bending or sagging at any point. Y

' The sash may be jointed in the center, as shown in Figure 4, wherein the sash I8 and I9 are provided with interlocking members 3d and 35 and the sash 2i and 22 with interlocking membersV 36 and 31. It will be noted that these members dovetail into Veach other and each is provided with a bead similar to the bead 2l against which the glass maybe placed. It will be understood that the glass may be held in the frames, or sash, by any other means or in any manner and the members may be shaped in any other design in order to facilitate mounting the glass therein.

Y The sash may be lockedV by a bar 38 which may be pivotally mounted on a block 39 on one sash Vand extend thru an opening 39, as shown in dotted lines in Figure 4, in the sash upon which it is mounted. This bar will also extend thru an opening 4I in the adjoining sash when the sash are in the closed position and in the lower part of the opening Ai is a slot i2 with a bevelled outer surface which the bar will engage as it is moved downward and it will be noted that the bevelled surface will clamp and hold the two sash rigid. A vertical bar 43 may be pivotally mounted on the bar 38 and may extend downward so that it may pass thru the lower member of the sash and also thru the end of the tongue 33 of the cross member 3 of the lower frame which will lock the sash in the frame to prevent them opening. It will be understood that a similar bar may be used on the upper sash, as shown in Figure 4, and

.it will also be understood that any other means ment of the sash or the frames in which the sash are mounted, another may be in the use of other means of hinging the sash in the frames, another may be in the use of rails of any other type or design for slidably holding the sash frames, another may be in .the design or arrangement of the counterweights, and still another may be in the use of other means for holding the sash and frames. Y 5

The construction will be readilyV understood Yfrom the foregoing description. In use the winn the upper sash frame may open outward whereas Y 5 the sash of the lower fram-e will open inward. ItV

will be noted that both sash may be opened With'2o Y both of the sash in the lowerposition and in this position both of the cross rails E and 3 will be at the bottom of the window so that the entire window opening will be free and unobstructed.

This window, therefore, provides percent 25 window opening and light and at the same timel may be thoroughly sealed and may otherwise operate as a standard double hung window.

The small sashmay he locked in the frames or otherwise secured therein during the Winter 30 or cold months and may be released so that they may ce opened during the summer months when it is desired to obtain as much window opening as possible and when the sash are in the locked position the entire frame with the sash will form 35 a very rigid member so that it may readily be raised and lowered in the usual manner.V

Having thus fully described the invention what I claim as new and desire to secure by Letters Patent, is: Y 40 A combination double hung Casement window of the type having sash frames hinged in U- shaped frames in which the lJ-shaped frames are slidable in a window frame, said U-shaped frames open at their upper ends and provided with 45 tongues connecting their lowerV ends. in whichV the tongues dovetail into the lower members of the hinged frames of the sash, and the central adjoining members of said hinged frames dovetail within eachother, the said hinged frames 50 of the upper sash swinging outward and the frames of the lower sash swinging inward, means locking the hinged frames in the U-shaped frames, and means locking said hinged frames together. 5
